The next-generation iPhone will have a 19-pin connector port instead of the usual 30-pin port

While many have speculated that the next-generation iPhone will have a smaller dock connector, it has finally been confirmed that the standard 30-pin port will be no more.

According to Reuters, which spoke with two sources close to the matter, the next iPhone's dock connector will shrink from a 30-pin connector port to a 19-pin port.

After using a 30-pin port for so many years (and for so many devices), why change now? Two reasons: a smaller port means smaller gadgets, and new opportunities for (read: money) for new accessories.

With a smaller dock connector, Apple can use create completely new product designs because it eliminates some of the 21 mm of space the 30-pin port uses. It could focus on making smaller devices while leaving more room for internal batteries.

The new dock connector also means that old 30-pin accessories like speakers and power chargers are no longer compatible with the new iPhone. Furthermore, this means that those who buy the new iPhone will have to buy entirely new accessories (like the speakers) instead of being able to recycle them from iPhone to new iPhone.

However, it was rumored that Apple may offer an adapter for those who want to upgrade to the new iPhone, but can't afford to replace all of their accessories.

According to Reuters' two sources, the main reason behind the shrinkage of the dock connector is to make room for the relocated headphone jack.

Lots of new iPhone rumors have been circulating lately, such as videos showing the unibody casing and leaked photos presenting the longer screen and metal backplates. These leaks confirmed a few new iPhone specs, such as the relocated headphone jack and metal antenna molded into the backplates.
